[HTML][HTML] Responsible investing: The ESG-efficient frontier

LH Pedersen, S Fitzgibbons, L Pomorski - Journal of financial economics, 2021 - Elsevier
We propose a theory in which each stock's environmental, social, and governance (ESG)
score plays two roles: (1) providing information about firm fundamentals and (2) affecting …

Regularized, fast, and robust analytical Q‐ball imaging

…, E Angelino, S Fitzgibbons… - … in Medicine: An …, 2007 - Wiley Online Library
We propose a regularized, fast, and robust analytical solution for the Q‐ball imaging (QBI)
reconstruction of the orientation distribution function (ODF) together with its detailed validation …

Apparent diffusion coefficients from high angular resolution diffusion imaging: Estimation and applications

…, E Angelino, S Fitzgibbons… - … in medicine: an …, 2006 - Wiley Online Library
High angular resolution diffusion imaging has recently been of great interest in characterizing
non‐Gaussian diffusion processes. One important goal is to obtain more accurate fits of …

[PDF][PDF] Assessing risk through environmental, social and governance exposures

J Dunn, S Fitzgibbons, L Pomorski - Journal of Investment …, 2018 - images.aqr.com
1 Much of the existing research has focused on the potential of ESG to influence expected
returns. We review such research below and find that it offers a fairly mixed message. For …

Long-only style investing: Don't just mix, integrate

S Fitzgibbons, J Friedman, L Pomorski… - Journal of Investing …, 2017 - papers.ssrn.com
We investigate two popular approaches to long-only style investing that are often considered
as potential starting points for smart beta investors: the “portfolio mix” that builds a style …

A fast and robust odf estimation algorithm in q-ball imaging

…, E Angelino, S Fitzgibbons… - … Imaging: Nano to …, 2006 - ieeexplore.ieee.org
We propose a simple and straightforward analytic solution for the Q-ball reconstruction of the
diffusion orientation distribution function (ODF) of the underlying fiber population. First, the …

A linear and regularized odf estimation algorithm to recover multiple fibers in q-ball imaging

M Descoteaux, E Angelino, S Fitzgibbons, R Deriche - 2005 - inria.hal.science
Due the well-known limitations of diffusion tensor imaging (DTI), high angular resolution
diffusion imaging is currently of great interest to characterize voxels containing multiple fiber …
